Below are Most important ASP.NET interview questions from caching aspectduring .NET Interviews .Day before yesterday I was at Mumbai Seepz giving a C# interview and below are some questions which where asked from ASP.NET aspect.

What are the various ways of doing caching in ASP.NET ?You can cache by using output cache directive , cache object and application object.The next thing the interviewer asked was regarding cache and application object.What's the difference between cache and application object ?In cache object you can define dependency properties , in application object you can not. In other words when the data which is cached changes even the cache object gets refreshed , but this is not the case of application object. You need to do a pull to refresh the data.This is a 100% sure question , how does ASP.NET page life cycle work ?.What are the different events which occur in ASP.NET page life cycle ?Init , load , validate , event and render.Remember SILVER ( Init , load , validate , event and render).What are HttpHandlers and HttpModules ?Both of these entities have one common goal , i.e. intercepting ASP.NET request and performing some operation on the request before it reaches the main object.But they way they intercept the request are different. HttpHandler intercepts the request using file extensions while HttpModule intercepts the request using Http events.You can refer ASP.NET page life cycle article here for details.

Why do we need session variables ?Http is a stateless protocol , after every request and response it forgets its original state. Session variables helps us to remember the state after every request and response.

Well frankly I did not clear this ASP.NET interview as I failed to answer simple .NET interview questions. So i will suggest every one to go through .NET Interview questions from this link. This article is part 1 of ASP.NET interview question and answers i will be soon posting by other questions in the coming week... Happy job hunting.

I have yet to remember a .NET interviewer who never asked about abstract classes, interfaces and object oriented interview questions . I am putting forward questions which comes around abstract classes and interfaces again and again...Hope every one benefits.
Normally the C# interviewer starts with.....

What is abstract class ?
Abstract class is a base class or a parent class. Abstract classes can have empty abstract methods or it can have implemented methods which can be overridden by child classes.

The next question i expectedwas on interfaces and yes there it comes.

What are interfaces?
Interface is a contract class with empty methods , properties and functions. Any class which implements the interface has to compulsory implement all the empty methods , functions and properties of the interface.Now the 1000% surequestion was bound to come difference between them...

What's the difference between abstract class and interface?
There are many differences, below are some key two differences :-

Abstract class can have some implemented methods and functions whileinterfaces methods and functions are completely empty.

Abstract classes are inherited while interfaces are implemented.

Abstract classes are used when we want to increase reusability ininheritance while interfaces are used to force a contract.

Can we create a object of abstract class or interface?
No we can not.Now the practicalquestion..

In what scenarios will you use a abstract class and in what scenarios willyou use a interface?
If you want to increase reusability in inheritance then abstract classes aregood. If you want implement or force some methods across classes must be foruniformity you can use a interface. So to increase reusability via inheritanceuse abstract class as it is nothing but a base class and to force methods useinterfaces.
Really friends having C# experience is one thing and crackingDot net and C# interviews is a different ball game all together .
